Comparison of PD-L1 (22C3) Expression in Paired Primary and Metastatic Breast Carcinoma
CONCLUSION: Our study showed a decrease in PD-L1 expression and disconnected molecular features during breast cancer progression. Repeating PD-L1 IHC testing could be considered in some specific metastatic sites if primary tumors were negative. Further studies are needed to identify other predictive factors for immune checkpoint inhibitor (ICI) therapy in patients with breast carcinoma.PMID:38492995 | DOI:10.1016/j.clbc.2024.02.010
